This man is Raúl Héctor Castro. He is 96 years old, a former Arizona governor, and a former United States Ambassador to El Salvador, Bolivia and Argentina. He was born in Mexico, and is a United States citizen.

Last month he was stopped by U.S. border patrol agents after residual radiation from a medical procedure he’d recently undergone triggered an alarm at a checkpoint in Tubac, AZ. The 96 year-old heart patient was then forced to exit his vehicle in the 100 degree Arizona heat and wait in a tent in a business suit, even as his companion begged the agents not to subject an elderly man to such treatment.

This is the third time the former governor and ambassador has been detained by border control. The first occurred years ago while he was repairing his own fence and agents stopped him and asked to see his work card — although they eventually desisted after Castro pointed out a sign by his farm entrance that read “Judge Castro.” The second occurred years later in San Diego, although that encounter ended shortly after someone recognized Castro and said “Governor, how are you?”
